4 Claims.

My invention relates to an improvement in an attachment for a duplicatormachine which consists of a postcard feedbox.

It is a feature of my invention to provide a feedbox for duplicatormachines which produce copies principally from stencils or from a systemknown as the spirit or direct process.

It is a further feature of my invention to provide a card feedbox whichwill hold a supply of cards in correct position for positive feeding toa duplicator machine and which may be positioned on the duplicatormachine with little adjust ment, thus doing away with the adjustment andpositioning of the ordinary guides used for work in the size of lettersand legal material. My device is so constructed that it may be placed inoperating position without the use of connections or tools. My device isused principally with postcards but it may be used with cards of anysize. Heretofore postcards had to be fed one at a time by hand to theduplicator machine, or a change of the large guides on the machines hadto be made, which change does not prove adequate.

It is a further feature of my invention to provide a card feedbox whichmay be positioned on a duplicator machine without disturbing the settingof the guides provided with the machine which may be set for letter orlegal sized paper.

It is an additional feature of my invention to provide a card feedboxwhich has resilient retaining posts which prevent more than one cardfrom being pushed into the machine at one time. I also provide risersupon which the cards are positioned. These risers cause the cards to layin the feedbox ina cupped position which facilitates forcing one of thecards from the feedbox at atime. r a

It is also a feature to provide projections or locating guides on thebottom of the feedbox to hold the same in rigid position on, the feedtable of virtually any type of duplicator machine.

These features, together with other details and objects, will be moreclearly defined and set forth in the following specification and claims.

In the drawings:

Figure 1 is a perspective view of a duplicator machine with my cardfeedbox placed in operating position thereon.

Figure 2 is a perspective view of my card feedbox.

Figure 3 is a bottom view thereof.

Figure 4 is a plan view of my card feed box positioned as illustrated inFigure 1, showing the feed arm of the duplicator machine in operatingposition over the same and the card partially removed from the cardfeedbox.

Figure 5 is an enlarged sectional view on the line 55 of Figure 4.

Figure 6 is a bottom view of an alternative form of adjustment for mycard feedbox.

My card feedbox A is composed of a bottom portion I0 which has securedto the sides thereof the longitudinal side wall portions I I. Thepartial end wall portions I2 are formed on the rear ends of the feedboxA projecting inwardly fromthe side walls II. tray A is open.

Adjacent the rear end of the side walls II I provide the openings I3formed in the side walls I I and which are adapted to receive a portionof the resilient cylindrical card retaining members I4 which partiallyproject through the openings I3. The card retaining cylinders I4 may bemade of rubber or any suitable material. The openings I3 extend the fullwidth of the side walls II except for a portion of the side wall II atthe top edge thereof. The casings I5 are secured to the outer surface ofthe side walls II and retain the cylindrical card retainers I 4 inproper position in the openings I3. The distance between the inner Thefront end of the feedbox surfaces of the rataining members I4 isslightly.

less than the width of the card B desired to be used with a feedboxtrayA. In addition the retaim'ng members I4 are maintained at a slight anglewith relation to the side walls II as illustrated particularly in Figure5. The angle of the retainer members I4 facilitates the placing of alarge number of cards between the members I4 and also the moving of thecards from the feedbox tray A by means supplied from the ordinaryduplicator machine C. The cylindrical retainer members I4 may beinserted into position from the bottom of the casings I5 through anindentation formed in the bottom It with the upper end of the retainerI4 butting against the upper edge of the opening I3.

The risers I5 are formed in the bottom I0 adjacent the rear partial endwalls I2 and the resilient card retaining cylinders I4. The risers- I5cause the card B to lie in a cupped position which facilitates movingthe cards from the feedbox A as particularlyillustrated in Figure 5 ofthe drawings.

I also provide 2. depending lug I6 which is centrally located on thebottom I0 of the feedbox A. The lug I6 is adapted to fit Within thegroove I! found on virtually all duplicator machines and the samepositions the feedbox A laterally on the feed bed I8 of the duplicatormachine C. The depending rear side lugs I9 are secured to the bottom I0and adapted to fit the transverse slot 20 found in the feed bed ofvirtually all duplicator machines. The lugs I9 maintain the feedboxlongitudinally upon the feed bed I8 of the machine A.

The lugs I6 and I9 may be adjustable as are the lugs 2I and 22illustrated in Figure 6 by providing the long angled portions 23 thereonand having formed therein the slots 24. The set screws 25 are positionedwithin the slots 24 and screwed 1n- 3 to the bottom I thereby allowingcomplete ad justment of the lugs 2| and 22 for duplicator machines whichare not universal in construction.

My card 'feedbox ,is used in "the following manner:

The cards B are placed within the feedbox A so that the side edges arein contact with the partial end walls 12, and the under side of thebottom card rests on the bottom and the risers l5, which tend tomaintain the cards in a cupped position. To facilitate the cupping ofthe cards the cards may be cupped slightly as they are placed in thefeedbox A tightly fit between the retaining members M. The cards B arealso, when inserted in the feedbox tray A, positionedagainstfthe'partial endwalls l2. The'members i4 tend to .''hold thecards within the'feedbox A under raslight tensionbut'which cards B maybe removed. therefrom by the :movement' of the feed arm D as it contactsthe upper card by means of the gripping members '26 as secured. thereto.With the cards B in cupped position as illustrated in Figure 5' only thelower corner edge of the card contacts the retaining members 14. Thusthe contact'of the cards B with the retaining members M is positive butonly on theunder lower corner thereof and not along the "full edge ofthe cardx-as would be the case if the cards werefiat and .not cupped. Inthis way cards, although positively held, are more easily removed thanif the oards were in aflat position.

The: card feedbox A with thecards positioned thereinashereinbefore-described, is then placed on thebed I 8'of the machine'Cso that either the lugs lil and IE or the lugs 2| and22 fit within theslots I1 and. 20. With the feedbox .A thus positioned, the machine C isthen set in operationgandthe' feed armD'with the gripping members" 26:is caused to contact the upper cardand move it'. toward the stencilroll of the'machine where animpression is made on the same. The card isthen carried from'the stencil roll to a receiving receptacle such as 21.

'The feedbox A may be made'of a size to handle the Government pennypostcard for the printing of the same with a duplicator machine. Mydevice fills a long felt need for a retainer which would quickly,efiiciently and easily hold postcards forprinting on a duplicatormachine. It is obvious that my feedbox tray may be made of a size tohandle any given sized cards.
